Landfall & Warp world

[Kaylesh]

603.6a: Enters-the-battlefield abilities trigger when a permanent enters the battlefield. These are written, "When [this object] enters the battlefield, . . . " or "Whenever a [type] enters the battlefield, . . ." Each time an event puts one or more permanents onto the battlefield, all permanents on the battlefield (including the newcomers) are checked for any enters-the- battlefield triggers that match the event.

If I use {warp world} and get a creature with landfall and a bunch of lands, will the ability trigger? If I read the rule above I'd say yes, or am I misinterpreting?

and what would happen with {Valakut, the Molten Pinnacle}, if over 6 mountains would enter? Is the trigger condition met?

[Kaylesh]

Simple answer is yes
Even if the object with landfall enters simultaneously with the lands you still get the triggers

Sweet, tx!
Mountain crush deck says hurrah. Abuse of mountains in any way possible.

And note for the {valakut, the molten pinacle} interaction, if 'kut had to be on the field before the other mountains when casting {scapeshift} it would basically be unplayable. {scapeshift} into valakut and 6 mountains, they all see each other enter and 6 triggers will go on the stack. If the lands didn't see each other enter {scapeshift} would be a much worse deck.

True. I just wasn't 100% sure, with the "if" clause and all, if Valakut would check the number of mountains as they entered, which would be 0. Happy it works, though.

I'm confused. What is it you're trying to say?

[LinkCelestrial]

Sounds like you should run {Scapeshuft}?

Same kind of question, I have {Lethal Vapors} and {Purphoros, God of the forge} or {Outpost Siege} out on the battlefield, what happens if i play a creature here?

Well, it's simple.  Let's say you had both.  A creature enters the battlefield.  Both Purph and Vapors trigger and you put them on the stack in whatever order you want, as you control them both.  Let's say Vapors resolves first and destroys the creature and puts it into your graveyard.  Outpost will now trigger because a creature left.  That trigger resolves, dealing some damage.  Purph's trigger now resolves as normal, since it doesn't care that the creature isn't there anymore.  A pretty smooth way to turn creatures into bolts.
